Magnesium is important because it is part of the makeup of bones and teeth, and every organ in the body uses the mineral in one way or another. Magnesium can be found in foods such as green leafy vegetables, nuts and whole grains.

Some medical conditions can alter the magnesium balance of the human body. Conditions such as irritable bowel syndrome, diabetes, pancreatitis, and kidney disease are some causes of a magnesium deficiency. People who ingest too much coffee or alcohol, or women who have regular heavy menstrual periods may also need more magnesium.

Magnesium is a contributor to heart health, lower blood pressure, may ease premenstrual syndrome, and can prevent migraine headaches, states the University of Maryland Medical Center. It may also help prevent type 2 diabetes and treat depression.

Other foods that have high levels of magnesium include, legumes, whole wheat flour, tofu, whole grains, oatmeal, chocolate, poppy seeds and peanuts. People who feel they don't get enough magnesium should seek the advice of a health care professional.
